A Message sent when the mouse pointer moves into an object. If there is a message handler by the same name in the message path, then it will be executed.

Message[]

Syntax:

mouseEnter

The mouseEnter message is sent only when the Browse tool is being used.

If two controls overlap, a mouseEnter message is sent whenever the mouse pointer crosses into a visible portion of a control. The control on the bottom receives a mouseEnter message only when the mouse pointer enters part of the control that can be seen. A control that is completely hidden by another control on top of it will never receive a mouseEnter message.

If the mouse button is down when the mouse pointer enters the control, no mouseEnter message is sent unless the mouse button is released while the pointer is still in the control.

If a control is shown (by changing its visible property to true or using the show command, and the mouse pointer is over the control when it is shown, LiveCode sends a mouseEnter message to the control.

Message handler[]

Example:

on mouseEnter -- show a Help field for the control the mouse is over
  show field (the short name of the target && "Help")
end mouseEnter

Use the mouseEnter message handler to perform an action (for example, display additional information or highlight a button) when the mouse pointer enters an object.
